It was strange because I just picked out about ten tunes to listen to, and put these two at the top of the list, and they both had the same editing cue.

The digital remastering often reveals the multi-track technique. Like Low Spark of High Heeled Boys, in which you can hear the other vocal tracks for the verse each time the verse comes back. That's a very common occurrence. you could even hear that a lot on the vinyl. They must have just recorded that piano progression for Low Spark and then sequenced it. The piano bit actually comes from an early Coltrane recording with McCoy Tyner. Not surprising, huh?
